Well it seems that netflix plans on putting the cost of adopting BluRay on it's HD customers.   Netflix is "planning on implenting a modest monthly premium for access to Blu-ray sometime this year."   There is no detail on how much they will be be charging their customers that rent BluRay movies.  So what does this "modest" charge on HD rentals mean to you?  If you're like the majority of the population probably nothing but right now the only think Netflix has going for it for me is it's a cheap service.  If the price bumps $2 or $3 a month more I'll cancel my account.  I barely watch more than three monies a month right now.  I might as well download a movie or head over to Blockbuster if I'm playing more per month for a service I rarely ever use.
